Title: Developing device and image forming device using same
Inventor: HIROBE JUNICHI
IPC: G03G15/00
Filed: 1993-11-09
Abstract: PURPOSE:To easily and inexpensively detect the occurrence of dew condensation by providing a means outputting a signal showing the dew condensation of a developing device when the electrical conductivity of developer is higher than a prescribed level. CONSTITUTION:It is discriminated whether a detection value C corresponding to the electrical conductivity of the developer in a developing container 41 is higher than a first reference value C1 or not. When the value C is lower than the value C1, the rotation of a toner replenishing roller 46 is stopped and the container 41 is stopped being replenished with toner. When the value C is higher than the value C1 and lower than a second reference value C2, the container 41 is continuously replenished with the toner. When the value C is higher than the value C2 and higher than a third reference value C3 besides, the signal showing the occurrence of the dew condensation of the developer is outputted by a microcomputer 82. Based on the outputted signal, a display for reporting the dew condensation is executed on an operation plate 91 by the control part 9 of a copying machine. When the value C is lower than the value C3, the display for reporting the depletion of the toner is executed on the plate 91.

Title: Switchable peak and average detection circuit
Inventor: DENISU RII ROJIYAASU
IPC: H03K5/1532
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To detect both a peak value and an average value of signals by a single circuit, by providing mutually supplementary switches each having an input terminal and an output terminal and switchable by a common switching input. SOLUTION: In a peak detection mode, an n-channel FETQ1 is turned on and a p-channel FETQ2 is turned off, whereby the circuit is operated as a peak detection circuit. In an averaging mode, the Q1 is turned off and the Q2 is turned on, so that signals are connected to a capacitor C1 via a resistor R1 thereby to form an averaging circuit. In this averaging mode, a positive input of an amplifier A1 is lowered either by a resistor R2 or by a regular leak current at an input terminal of the A1. Accordingly, an output of the A1 is decreased, inversely biasing a diode D1. In consequence, the A1 is effectively shut from the C1.

Filed: 1988-11-05
Abstract: PURPOSE:To form a fine pattern of <=1mum by an inexpensive laser light source by providing a shielding plate which has an opening in a predetermined shape in front of an objective and converging laser light only through the opening. CONSTITUTION:When the laser light L is converged on resist 14 on a semiconductor 12 through the objective 10 to form the fine pattern, the light shielding plate 16 having the opening 18 in the predetermined shape is arranged above the lens 10. Then the laser light L is passed through only the opening 18 and then cut partially to cause diffraction to obtain such a Gaussian distribution that the light intensifies or weakens itself locally. Consequently, the light intensity distribution of the laser light is much steeper than when there is not the shielding plate 16, so not a short-wavelength laser, but the inexpensive laser light source is used to form the fine pattern.
